Hello, I am "writing" (in fact I am getting a lot of code from /usr/src/usr.bin/vmstat) an Orca data collector for FreeBSD. I think it would be great to have the performance data available in Orca. I am thinking about representing the following parameters: CPU load CPU usage (user, system, interrupt, idle). żDo you think it is better to add nice + user to have a single "user" value, or is it better to separate them? Spawned process/sec Number of processes Interface stats: in, out (bps) in, out (packets) errors/s "nocanput" (perhaps packets not send because of buffer outages?) "deferred" collisions TCP bits/sec TCP packets/sec TCP retransmissions + duplicates TCP new connection rate TCP open connections TCP reset state TCP listen drop rate MBUFs Disks: operations/sec transfer rate transfer size run % or time to complete an operation (BTW... is it possible to get read and write statistics instead of a sum?) Cache hits (inode and directory) Memory (usage, etc). Any more interesting parameters? An example of Orca can be seen in http://www.gps.caltech.edu/~blair/orca/. It is really useful to watch the system performance. Borja. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
